Any pointers/advice for starting CUL?

[Mirarara]

Im sure most, if not all, of us agree that getting more cross class skills makes everything easier. But single class CUL would probly be the best single class to go. As a single class youd be able to put your specialist on, so youd get byregots miracle(rather then blessing). You get versions of careful, manipulation, waste not(via prudent), and rapid. With all your tricks, 1 star should be doable.

I would rather you show me a rotation where you can get a high HQ chance for lv 70 1 star recipe with 1320/1220/522 stat without cross class skill. It's kinda impossible to do it consistently without ingenuity I/II.

There was a discussion in the 4.05 Crafting disappointment thread if 1-2 star can be done by a single class.

In that thread, cross class skill at lv 15 is used.

Edit: By High HQ chance I mean you can get it 90% of the time, including the chance from failing non 100% action.

Edit2: It's possible to do it with at least 90% success rate if you have cross class skill at 15, but the simulation I tried required 1373 craftsmanship (achievable by pentamelding), which is expensive for a new crafter.
